The value of the z-score for the value of sample 48 will be negative 0.4.
The z-score is a statistical evaluation of a value's correlation to the mean of a collection of values, expressed in terms of standard deviation.
The mean is 50 and the standard deviation is 5.
Then the value of the z-score for the value of sample 48 will be
z = (x - mean) / (standard deviation)
Then we have
z = (48 - 50) / (5)
z = -2 / 5
z = -0.4
